This Year's CYCLO X Series has some new and exciting changes as the long standing Boulder Cyclocross Series and CYCLO X Series have merged to form the NEW Shimano CYCLO X Series powered by Boa Technology.  Each venue is set up to test and challenge the athlete in unique ways, so come Decemeber we're able to crown the best cyclocross racer in Colorado!  When it comes time to train get ready for; the power sucking grass of Interlocken, the tight woods of Xilinx, the grand stair case of Westminter, the run ups at Louisville, the sands of Boulder Res, the lights of Castlerock, plus many more iconic elements at each venue!


The CYCLO X Series will feature live chip timing!  Friends and family can track the lap splits and action remotely on their smart phones or home computers.  Once athletes cross the finish line they'll have instant access to all their splits at our live TV Timing Tent, located in the event expo!


The 8 race Shimano CYCLO X Series, powered by Boa Technology, is the longest running series in the state, with its roots stretching back to 1999.   For 2013 the staple of venues return; Valmont, Xilinx, Interlocken, Boulder Reservoir, Louisville, and Westminster, along with some new additions in Flatirons and Castlerock
